A coin is tossed repeatedly and the results are noted. After 250 tosses, the empirical probability of obtaining a head is reported as 53.
a. (i) Calculate the number of times a head was obtained.
b. (ii) Determine how many times a tail was obtained.
c. (iii) Verify that the sum of the empirical probabilities of the two complementary events “head” and “tail” is 1 for this experiment.
